FEATURES & HIGHLIGHTS

Simply get on and off.

The completely redesigned step-through frame made of aluminum is lighter, more stable, and even more harmonious in its lines. Getting on, riding off, stopping – everything feels instantly familiar, intuitive, and agile. The new design reduces the weight by approximately 3 kg and has a cleaner, more modern look.

Direct, dynamic, natural: the new torque sensor.

The Quartz Driving will be even smarter in 2026.

The integrated torque sensor reacts precisely to your pedaling force and delivers natural, finely dosed support – ideal for stop-and-go traffic, starting on hills, or smooth cruising through the city. More control, faster motor response, significantly smoother riding dynamics.

Powerful rear-wheel drive – now even more confident.

The proven 48-volt rear motor with 55 Nm of torque remains a real powerhouse.

In combination with the new sensor system, it accelerates faster, more smoothly and efficiently – uphill, with luggage or on long journeys.

On the go with stamina.

The integrated 644 Wh battery ensures a long range for everyday use.

It can be easily removed and charged externally. The new charging port makes the system even safer and compatible with the app configuration of all current Deruiz models.

Safe braking – in any weather.

A major upgrade: The new hydraulic disc brakes with 180 mm discs front and rear ensure strong, reliable braking power – dry, wet or downhill.

More control, less effort, significantly more safety.

Mudguards in a new design.

Deruiz's new double-layered aluminum mudguards are robust, stylish, and free of rubber components. Minimalist, high-quality, and perfectly matched to the new frame design.

Tires you can rely on.

New: Schwalbe Road Cruiser with K-Guard puncture protection, reflective sidewalls, and quiet, comfortable rolling characteristics. Ideal for city traffic, gravel roads, and everyday riding – stable, safe, and durable.

More space for everything that matters.

The new head tube area features four additional mounting points – compatible with all current Deruiz front baskets and racks. More carrying options, cleanly integrated, stable and versatile. The integrated rear rack carries up to 25 kg and is fully compatible with panniers, baskets and the Quick Mount system.

Whether it's shopping, laptop or weekend gear – everything finds its place.

Smartly connected – with the Deruiz Ebike App.

The Deruiz Ebike App is your digital co-pilot: it connects to the bike via Bluetooth, shows range, GPS position and route recordings.

It keeps everything at hand – from battery status to customer support.

Does my inseam fit this bike?
stride

First measure your inseam. If the measurement is within the green bar, the model fits you.

How to measure your stride length

Take a book and stand with your back to the wall. Clamp the book between your legs. Pull it into your crotch, as if sitting on a saddle. Hold the book parallel to the floor along the wall behind you. Make a line on the wall behind you/top edge of the book. Now measure the distance to the floor. Please take the measurements with your shoes on.

If you choose a bike with a top tube, make sure that the height of the top tube is equal to or less than your inseam (see picture).

(measure the height of the top tube at the point where you are standing in the bike)
